About Us

The vision of NAO is to build the premier destination, where wealth building becomes a true and meaningful experience.

We have recognized that many retail investors lose their wealth by aiming for fast and easy money instead of long term wealth building.

In comparison, professional investors and Family Offices have a much deeper knowledge in markets and a better relationship to investment companies.

With strong knowledge in finance and tech product building, we want to fight inequality in investing by creating a new kind of investment club for digital natives.

Business Model

NAO offers a solution based on three fundamental principles that enable everybody to invest like a professional investor:

  • First we are scouting the market for exclusive wealth-building opportunities with our network and experience
  • Second we are curating and structuring investments for long term wealth building
  • Finally we use a co-investing approach leveraging our platform to make these investments possible for everyone

Using this approach NAO enables everybody to invest with min €1.000 in asset classes like PE, VC and Art funds as well as real estate, collectibles and investment banking products, issued exclusively for NAO.
